Elton John has called on members of the public worldwide to get involved in his "Love In My Blood 2.0" campaign.

The British star is asking supporters to post a selfie on social media using the hashtag #loveisinmyblood and make the global sign language symbol for "I love you," as demonstrated by David Furnish in the image.

The campaign, which was first launched by the Elton John AIDS Foundation last year, is a way of showing love and solidarity for lesbian, gay, bisexual and transgender communities around the world, who are at greater risk of contracting HIV because discriminatory laws cut off their access to information and treatment.
